The research of electromagnetic conducted coupling in transmission-line networks

The electromagnetic topological theory has important applications value in analyzing the problem of electromagnetic interference (EMI). The BLT equation of the line network and the method of calculation in engineering are presented. The electromagnetic topology model of single transmission-line networks is built. The responses on junctions of the transmission-line networks with impulse interference sources of different injected positions and numbers are studied. The responses of junctions are related to injected position and numbers. These results are proved to have an important significance in researching the law of conducted coupling to the electromagnetic pulse on complicated network.
